Ralph invested in a mutual fund and at the end of 20 years he has $14,300 in his account. If the mutual fund returned an average

Semenov [28]

Answer:

$\$5,500$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=20\ years\\ P=?\\ A=\$14,300\\r=8\%=8/100=0.08$

substitute in the formula above

$14,300=P(1+0.08*20)$

$14,300=P(2.6)$

$P=14,300/(2.6)$

$P=\$5,500$

Solve the equation 4 sin (x +30°) = 2 for 0 < x < 365

tatuchka [14]

$4 \sin(x + 30) = 2 \\ \sin(x + 30 ) = \frac{2}{4} \\ \sin(x + 30) = \frac{1}{2} \\ \sin(x + 30) = \sin(30) \\ x + 30 = 30 \\ x = 30 - 30 \\ x = 0$

Hence, x = 0°, 180° and 360° Ans

Find the difference. (12m + 1) - (5m - 4)

Law Incorporation [45]

Answer:

7m + 5

Step-by-step explanation:

1) Simplify.

(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4

2) Eliminate unnecessary parenthesis.

(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.

3) Combine like terms.

12m - 5m = 7m, 4 + 1 =5 -> 7m + 5

The solution is 7m + 5
